Thanks, Thomas. I was hoping the Terminfo expert was reading.

I'll change it to something like "Slang and Ncurses sometimes use
different capabilities of the terminal, so you may be able to work
around a broken terminfo entry by using a different library".
Hmm. Something I've noticed in Ncurses-based apps is that blank areas
don't erase text. For example, in Pinfo, when I page down, some of the
previous screen still shows in the blank areas. It's probably a common
problem with a simple explanation. Some capability that needs to be
set or unset in my terminfo entry?
